It is a processing unit that performs processing for accumulation.

The storage unit 25 is a storage unit configured by a storage device such as a nonvolatile memory or a hard disk drive, and stores device information 25a, feature amount information 25b, threshold information 25c, and reception information 25d. The device information 25a is information such as the date of manufacture, model, and device identification number of the banknote handling device 20.

The feature amount information 25a is information including the optical feature amount and the magnetic feature amount of the banknote deposited in the banknote processing apparatus 20. Note that the threshold information 25c has already been described with reference to FIGS. 4 to 7, and the reception information 25d has already been described in the description of the reception unit 24c, so description thereof is omitted here.

Next, a processing procedure executed by the banknote processing apparatus 10 provided in each bank will be described with reference to FIG. FIG. 8 is a flowchart showing a processing procedure executed by the banknote handling apparatus 10 provided in each bank. As shown in the figure, the user information acquisition unit 15a acquires user information 16a (step S101). The feature amount information acquisition unit 15b acquires feature amount information 16b (step S102).

Subsequently, the banknote category is determined by the banknote classification unit 15c, and when the banknote category is 2 or 3 (step S103, Yes), the banknote classification unit 15c selects the banknote 100 with the category 2 or 3, The stacker 13 is instructed to store in the dedicated stacker for category 2 or 3 (step S104).

And the transmission part 15d transmits the user information 16a, the feature-value information 16b, and the apparatus information 16c to the banknote processing apparatus 20 (step S106), and complete | finishes a process. When the determination condition of step S103 is not satisfied (step S103, No), the banknote sorting unit 15c instructs the stacker 13 to store the category 4 banknote in the general stacker (step S105). The process ends. Category 1 banknotes are returned to the user.

Next, a processing procedure executed by the banknote processing apparatus 20 provided in the central bank will be described with reference to FIG. FIG. 9 is a flowchart showing a processing procedure executed by the banknote processing apparatus 20 provided in the central bank. As shown in the figure, the feature amount information acquisition unit 24a acquires feature amount information 25b from the deposited banknote (step S201).

Subsequently, the match search unit 24b reads the received information 25d (step S202), and compares the device information 16c and the device information 25a to determine whether the models are the same (step S203). If the models are the same (step S203, Yes), the same model threshold value included in the threshold information 25c is used (step S204), and a match determination process is performed (step S206).

On the other hand, when the determination condition of step S203 is not satisfied (step S203, No), the different model threshold value included in the threshold information 25c is used (step S205), and a matching determination process is performed (step S206).

Subsequently, the match search unit 24b determines whether or not the match determination processing result is a match (step S207), and if the match is found (step S207, Yes), the corresponding user information 16a is received information 25d. (Step S208). Then, when the search for all the feature amount information 16b included in the reception information 25d is completed (step S209, Yes), the process ends.

In addition, when the determination condition of step S207 is not satisfied (step S207, No), when the determination condition of step S209 is not satisfied (step S209, No), the processes after step S202 are repeated.

By the way, in FIG. 9, the same model threshold value indicating a determination frame with a narrow effective range and a different model indicating a determination frame with a wide effective range based on whether the models of the banknote processing apparatus 10 and the banknote processing apparatus 20 match. In the first match determination, a default determination frame with a narrow effective range is used, and when there is a mismatch in the first match determination, an enlargement determination frame with a wide effective range may be used. .

FIG. 10 is a flowchart showing a modification of the processing procedure executed by the banknote processing apparatus provided in the central bank. As shown in the figure, the feature amount information acquisition unit 24a acquires feature amount information 25b from the deposited banknote (step S301).

Subsequently, the match search unit 24b reads the received information 25d (step S302), uses the default determination frame (step S303), and performs a match determination process (step S304).

Subsequently, the match search unit 24b determines whether or not the match determination processing result is a match (step S305), and if the match is found (step S305, Yes), the corresponding user information 16a is received information 25d. (Step S306). Then, when the search for all the feature amount information 16b included in the reception information 25d is completed (step S307, Yes), the process is terminated. In addition, when the determination condition of step S307 is not satisfied (step S307, No), the processing after step S302 is repeated.

On the other hand, when the determination condition of step S305 is not satisfied (step S305, No), the re-determination process is performed after using the enlargement determination frame (step S308) (step S309). The redetermination process in step S309 is the same as the coincidence determination process in step S304, except that the determination frame to be used is an enlargement determination frame.

Then, the match search unit 24b determines whether or not the match determination processing result is a match (step S310), and if the match is found (step S310, Yes), the corresponding user information 16a is received from the reception information 25d. Obtain (step S311). Then, when the search for all the feature amount information 16b included in the reception information 25d is completed (step S307, Yes), the process is terminated. If the determination condition in step S310 is not satisfied (step S310, No), the process in step S307 is performed.

In FIG. 10, when the match determination processing result in step S304 does not match (No in step S305), a uniform enlargement determination frame is used in step S308. However, the present invention is not limited to this, and a plurality of enlargement determination frames having different degrees of enlargement may be switched and used.

For example, when the model determination process shown in FIG. 9 (see step S203 in FIG. 9) is combined and the same model is used, the first enlargement determination frame with a small degree of expansion is used. Each of the second enlargement determination frames having a large degree of enlargement may be used.

By the way, until now, the case where a matching search is performed based on the characteristic amount unique to the banknote has been described, but as a search success rate of the matching search is improved by giving a new characteristic amount to the banknote. Also good. Therefore, in the following, the banknote processing system 1a that gives a new feature amount to the banknote will be described.

FIG. 11 is a diagram showing an outline of the banknote processing system 1a according to the modification. As shown in the figure, the banknote processing system 1a is composed of a banknote processing apparatus 10a installed on the bank side and a banknote processing apparatus 20a installed on the central bank, and banknote processing installed on the bank side. The apparatus 10a differs from the banknote processing apparatus 10 shown in FIG. 2 in that the additional printing 101 is performed on the deposited banknote.

Specifically, the banknote processing apparatus 10a shown in FIG. 11 includes a printing unit (not shown), and prints characters, symbols, and patterns on the deposited banknote. Here, it is assumed that the printing unit performs printing on the banknote using volatile ink that disappears after a predetermined period of time, ink such as ink that becomes colorless at a predetermined temperature or higher. In this way, the use of ink that disappears or becomes colorless under predetermined conditions does not hinder the recirculation of banknotes.

Further, as the ink used by the printing unit, it is possible to use an ink that is visible with visible light, or an ink that is not visible with visible light and is visible with infrared light. In this way, by using ink that is visible with infrared light, it is possible to conceal that the printing has been added to the banknote, and it is possible to prevent fraudulent acts from being carried out when the banknote is transported. .

Here, it is assumed that the feature amount information acquisition unit 15b acquires the feature amount information 16b for the banknote on which predetermined printing is performed by the printing unit. In addition, as for a printing part printing only with respect to the banknote determined as the category 2 or 3 by the banknote classification part 15c, as feature amount information acquisition part 15b acquires the feature-value information 16b about the banknote in which printing was performed. Also good.

On the other hand, in the banknote processing device 20a installed on the central bank side, the feature amount information acquisition unit 24a acquires the feature amount information 25b for the banknote on which predetermined printing has been performed by the printing unit of the banknote processing device 10a. Note that when the feature amount information 25b is acquired, the printing by the printing unit of the banknote processing apparatus 10a installed on the bank side is not lost.

Thus, the success rate of the match search by the match search unit 24b can be improved by adding a predetermined print to the banknote and increasing the number of elements constituting the feature amount information.

By the way, until now, when banknote processing apparatus 20 performs the search (match search) of whether the feature-value acquired with banknote processing apparatus 10 and the feature-value acquired with the banknote processing apparatus 20 correspond. However, in the banknote processing device 20, only the feature amount acquisition processing may be performed, and a matching search may be performed by a determination device connected to the banknote processing device 20.
